2008 HUMMER H3 set time

Reducing Speed While Using Cruise
Control

Press and hold the set button until you reach the
desired lower speed, then release it.
To slow down in very small amounts, briey press
the set button. Each time you do this, you will go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle
slows down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control works on hills depends
upon your speed, load, and the steepness of the hills.
When going up steep hills, you might want to step on the
accelerator pedal to maintain the vehicle speed.When going downhill, you might have to brake or shift
to a lower gear to keep the vehicle speed down. Of
course, applying the brake turns off the cruise control.
Many drivers nd this to be too much trouble and do not
use cruise control on steep hills.
Ending Cruise Control
To turn off the cruise control, do one of the following:
Step lightly on the brake pedal.
Move the cruise control switch to off.
Lightly tap or press the clutch, if you have a manual
transmission.
Erasing Speed Memory
When you turn off the cruise control or the ignition, the
cruise control set speed memory is erased.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P) if you have an
automatic transmission.
The light sensor determines it is daytime.
When the DRL are on, no other lamps are on. The
instrument panel will not be lit up either. For vehicles rst
sold in Canada, if parking lamps are manually turned
on, DRL will stay on.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
To turn off the DRL, seeExterior Lamps on page 3-15.Vehicles rst sold in Canada cannot turn off DRL unless
certain conditions are met. SeeExterior Lamps on
page 3-15.
Automatic Headlamp System
When it is dark enough outside, the automatic headlamp
system will turn on after the transmission has been
shifted from PARK (P) to DRIVE (D). The headlamps,
taillamps, sidemarker, parking lamps, roof marker lamps,
and the instrument panel lights will turn on at normal
brightness. The radio lights will become more dim when
the headlights are off compared to when the headlights
are on.
Your vehicle has a light sensor located on the top of the
instrument panel. Be sure it is not covered, or the
system will be on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp system so
that driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system will only be affected when the
light sensor detects a change in lighting lasting longer
than the delay.
3-17

The air conditioning will not function if the fan is turned
off. If air conditioning is selected with fan off, the
indicator light ashes three times and then turns off.
A slight change in engine performance may occur when
the air conditioning compressor shuts off and turns
on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
The air conditioning system removes moisture from the
air, so sometimes there may be a small amount of
water dripping underneath the vehicle while idling or
after turning off the engine. This is normal.
9(Fan):Turn the center knob on the control panel to
control the fan speed. Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
9(Off):Turn the center knob to this position to turn
the fan off. With the fan off, you may still experience
airow from the system that increases with vehicle
speed depending on the mode and temperature settings.
Enable recirculation mode to stop this airow from
occurring.
@(Recirculation):Press the center of the fan
control knob to recirculate air inside the vehicle and
prevent outside air from coming in. It can be used
to prevent outside odors from entering the vehicle and
cool the air inside the vehicle more quickly. Pressthis button to turn the recirculation mode on or off. An
indicator light on the button comes on to show that
the recirculation mode is activated.
Recirculation is available in the bi-level, and vent
modes. Recirculation is not available while in oor,
oor/defog and defrost mode. If recirculation is selected
in these modes, the indicator ashes three times
indicating it is not available in that mode. When the
recirculation mode is turned on, the air conditioning turns
on automatically.
When it is hot enough outside, the recirculation mode
may turn on automatically to help improve cooling
performance. The indicator light will be lit to show this
mode is active. If the recirculation button is pressed
while in this mode, the light will ash three times
and stay on to indicate that recirculation may not be
shut off.
The right knob on the control panel is used to direct the
airow inside the vehicle. In-between modes are
available by moving the right control knob between
modes with symbols. The in-between mode is a
combination of the two modes that the control is
centered between.
Turn the right knob to select one of the following modes:
H(Vent):This mode directs air to the instrument
panel outlets.

Audio System(s)
Determine which radio your vehicle has and then read
the pages following to familiarize yourself with its
features.
{CAUTION:
This system provides you with far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and you
or others can be injured or killed. Always keep
your eyes on the road and your mind on the
drive — avoid engaging in extended searching
while driving.
Keeping your mind on the drive is important for safe
driving. SeeDefensive Driving on page 4-2. Here
are some ways in which you can help avoid distraction
while driving.
While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering wheel
controls if the vehicle has them.
Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer/retailer. Also, check federal rules covering
mobile radio and telephone units. If sound
equipment can be added, it is very important to do
it properly. Added sound equipment may interfere
with the operation of your vehicle’s engine, radio,
or other systems, and even damage them. Your
vehicle’s systems may interfere with the operation
of sound equipment that has been added.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. SeeRetained
Accessory Power (RAP) on page 2-20for more
information.
